Dr. Weindruch is a University of Wisconsin Professor of Medicine and a scientist at the Geriatric Research, Education and Clinical Center at Madison's VA Hospital. For 26 years, he has studied the retardation of aging by
caloric restriction (CR). He directs a National Institute on Aging (NIA)-funded training program in "The Biology of Aging and Age-Associated Diseases", the Shared Aging Rodent Facility, and the Aging Research Group at the Wisconsin Regional Primate Research Center.

He earned his B.S. and M.S. in Biology at the University of Illinois (Urbana) and his Ph.D. (1978) in Experimental Pathology at UCLA under the direction of Dr. Roy Walford. He has authored two books and more than 130 scientific articles. In 1988, Drs. Weindruch and Walford published "The Retardation of Aging and Disease by Dietary Restriction," which is widely regarded as the founding text for this growing field.

Dr. Weindruch has received several awards for his research including the 1998 Kleemeir Award from the Gerontological Society of America, the 2000 Nathan Shock Award from the NIA and the 2000 Glenn Award from the Paul Glenn Foundation. He is directing a large, NIA-funded study in rhesus monkeys to determine whether CR retards the aging process in primates. He also oversees other NIA-funded projects exploring the mechanism by which CR retards the aging process in mice.
